In an SPH system, I specified the P-link module as 'unimplemented' and the program execution time was extended. Why?
When the P-link module is specified as 'unimplemented' and no P-link module exists in the system, attempting to access the P-link memory using a contact, coi...

With D300win, I used a non-procedural FB (_C_free) in a program for compilation and an error occurred. What is the cause of this problem?
One possible cause is that common FB _C_COM is not registered with the library.
For communication-related expansion FBs including _C_FREE, register common...
